Abstract

Abstract By a careful analysis of the form of the current implied by the boundary conditions satisfied by the solution of Poisson's equation, we generalize previous results and show that irreversible redox processes at a self similarly rough (fractal) electrode give rise to a skewed arc plot in the complex impedance-plane. We also discuss the form of scaling relations obeyed by the current at the electrode to ensure the validity of Ohm's law in the solution.
